'In all burners of this general character, considerable difliculty is encountered in the proper operation or use of the burner, resultm from poor, medium or strong drafts re furnis ed by many different sizes and styles of flues, and a great percentage of such troubles rises from the formation of soot or carbon, which is the cause of both fire and filth. Then again, the improper mixture resulting %"from oor combustion, furnishes an insufiicient and unsatisfactor heat, notwithstanding the consumption an excessive amount of fuel. Furthermore, it is not infrequent to have the flame extinguished in such burners M by .an excessive draft, which sometimes causes explosions with the resultant damage.

It is therefore the purpose of this invention to provide means of novel construction to overcome the above enumerated objects,

0 by making it pomible to obtain a proper mixture and a consequent proper combustion and operation of the burners with any kind of draft, that is to sag whether the draft is ood, r or medium, the invention particuarlyeliminating the troublesome formation of carbon.

Another object of the invention resides in the provision of means whereby access may be readily had to the interior of the burner, or any part which requires cleaning from time to time, 'or for any purpose whatsoever. The nature and advantages of the invention will be better understood when the following detailed description is read in con- B nection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts .as claimed.

In the drawings forming part of this 59 application, like numerals of reference indicate similar parts in the several views, and wherein:

Figure 1 is a top plan view of the burner Figure 2 is a side elevation partly in section showing the component parts separated.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1 showing the arrangement of, parts when only a poor draft is obtainable.

Fi re 4 is a view similar to Figure 3 showing the arrangement of parts when there is a strong draft.

Figure 5 is a detail view of one of the adjusting rings.

Referring to the drawings in detail, indicates the base of the burner which is substantially dish shaped or curvilinear as shown, although the central portion of the base is elevated as at 11 and formed with a series of concentrically disposed grooves or troughs 12. Then again, the center of this base is rovided with a fuel inlet opening 13 in whic one end of a supply pipe 1s threaded. The bottom adjacent one edge is provided with. an overflow opening 15 1nto which is threaded an overflow pipe 16. Projecting from this bottom but forming an integral part thereof, are air inlet passages 17, the latter being arranged at dlametrically opposed points above the base as .clearly illustrated in Figure 1. It will be noted that the air inlet passages 17 are on the out side of the bowl portion of the base, thus preventing the air -whichwpasses upwardly through the opening 17 from cooling the bowl as quickly as where ,the air openings are located inside the bowl ptrtion of the base, This is a very important feature in burners of this character, as it allows the fire to be turned down very low, which cannot be done with burners in present day use where the air inlet openings are arranged on the inside, due to the cooling effect of the air on the bowl portion of the burner. The shape of these openings can varywithout departing from the spirit of the invention and this is also true in regard to the size of such passages. The wall of each passage is cut away at the upper end'thereof to provide a recess 18, the purpose of which is to be presently describe t The top of the burner is as shown, formed with a depending centrally arranged portion 19, which is preferably of cylindrical formation in cross section, and adapted to be arranged immediately above the elevated central portion 11 of the base 10 to direct the draft or air downwardly conduits, in a manner whereby the top member is supported upon the base. In other words, each conduit or flue is provided with an annular flange or shoulder 21 which reposes upon the bottom of the recess 18 above referred to. r

The top member is provided with a central opening arranged immediately above the portion 19, and this opening is normally closed by a cap 22 formed with a flange 23 which reposes upon an inwardly directed flange 24 forming an integral part of the top of t - burner, so that a proper mixture and commember. The flange 23 e cap is pro- "videdwvith draft openings 25 as is also the flange 24 of the top member, the openings in the latter being indicated at 26. The cap is not only removably associatedwith the top member but it is susceptible of being rotated for the purpose of allowing the openings thereof to be-moved into or out of registration with the openings of the flange 24, with a view of allowing a portion of the excessive air to pass outwardly through these openings instead of forcing all air downwardly against the bottom or bowl of the burner. The cap is provided with an opening 27 to facilitate handling of the cap or forthe purpose of removing it from the top member or for turning it for the purpose just stated. .The invention embodies a plurality of adjusting rings 29 of a shape to correspond to the configuration of both the recess 18 and the cross sectional configuration of each conduit or flue 20. These rings being used to adjust the top member with relation to the base or bowl of the bustion for a proper operation of the burner may be obtained with either a poor, or medium It is of course to be under- 'stood vl that a numberof these rings will be provided for each burner, the rings varying in dimensions so that a proper adjustment of the top member'with relation to the base or bowl of the burner can be obtained to meet. an requirement. U n inspection of I airgand vaporized oil wi taken care of by the overflow course upon the draft condition, and when these rings are used they are positioned in the manner shown in Figure 4. When the use of these rings are resorted to, there is one ring associated with each fluid or conduit 20, the rings being interposed between the flanges of each'flue, and the bottom of the recess 18 formed on the base member. Consequently, the tubular portion 19 is spaced the required distance away from the bowl or base to insure theproper'mixture of air and vaporized oil. The adjustment of the top member with relation to the base in this manner makes it possible to obtain a proper combustible mixture with any sort of draft condition, thus obtaining a most satisfactory flame-and heat with the consumption of a minimum amount of fuel, but more particularly, overcoming the objectionable features herein above enumerated, and particularly the objectionable formation of carbon. I

The burner is used in the usual. well known manner, the base 10 being designed to provide what may be termed a bowl in WhlCh a riming charge is initially arran ed, th1s charge being conveyed to the bow through the fuel supply pipe. 'This charge is then ignited, and permitted to burn for the purpose of properly heating the bowl after which the oil is allowed to I passages through theflue or conduit 20 which conveys the air into the centrally arranged tubular portion 19 passing downwardly through this portion into the base as in other burners. Any overflow of oil will be ipe above mentioned, while any excessive am or draft can be regulated by means of the damper which the cap of the top member actually provides.

While it is believed that from the fore-. going description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limited myself to what is herein shown Y and described and that such changes may be resorted to when desired as fall within the scope of what is claimed;

Having thus described the invention, I claim: y g is 1. In an oil burner, a base designed to form a' fuel receiving bowl, a fuel sup 1y.
